Tymate Tire Pressure Monitoring System - Full-Color Screen Design, 6 Alarm Modes, CLA Charging Method, Simple Installation and Setup, with 4 Advanced External Tmps Sensor (0-0.6 Bar/ 0-87 PSI)

This is a great aftermarket option for a TPMS, as I was looking for something easy to keep track of my tire pressure in my old 2002 Toyota 4runner. It just plugs into your cigarette lighter and has easy, concise directions on how to set it up. Easy to see at night as well, and the price of the unit is just right. I've had it for about 3 months now and it still works fine no problems. Highly recommended!

Update 4/21: unit still randomly works, issue still persists dropping all reading on road trips. Seems like driving for longer than an hour straight the sensors just stop working. Update 2/21: rating changed to 1 star, this is my third unit and will be getting of this one and calling it quits with this brand. Unit doesn't connect 80% of the time. Sometimes it works for almost a week then will disconnect and not read for several days until I repair manually or at times it will randomly start working. Currently looking at it and its reading 2 of the 4 sensors, yesterday was 1 then all 4 then none. I want to give this 5 stars but i had some bad luck with two other units before the third one finally worked and even that was a real pain. First one I ordered the display was dead and wouldn't allow me to move between screens, second unit the sensors wouldn't pair no many how many times I tried. The third unit was still a pain as well as the sensors wouldn't pair as well however after many tries they finally did. IF YOU HAVE ISSUES PAIRING READ A LITTLE MORE! Take all the sensors off and set aside away from the display and do not move the sensors for at least 10-15min. When ready plug the display into power and enter pairing mode by hitting the button 5x quickly. You will see several numbers with a number in the middle which starts at 0 then will switch to 1,2,3. While in this mode install Front left sensor, you should hear a beep coming from the display, hit the side button once now install front right sensor and repeat to back right then back left. It might take a few tries but the key seems to be separating the sensors from the display for 10+min before assigning the sensors if they won't pair initially. Now that the sensors are working it does its job as expected and fairly accurate. Display is hard to see in bright sunlight but manageable. Time will tell how it holds up but pairing was the biggest problem.

Great product! Used it on both of my cars for separate cross country trips. They worked great for the trip without any issues. The readings were pretty accurate. I had problems after filling air at a Costco on a couple of occasions. The issue was not particularly the product, but the technician not knowing the product and it's feature. Technically, I can't blame them either, but they don't allow customers to fill the air. You need to be very careful removing the sensors. Obviously, they need some kind of gaskets to seal the sensors. When you remove them, sometimes the inner gasket get stuck on the valve stems or come loose and fell off during taken off. If you lose it, your sensor will cause a leak and eventually get a flat tire. But the indicator inside helps you recognize that well before to prevent losing all the air if you act quickly. All you need to do is to remove the sensor. You can avoid all of these issues if you pay attention to the gaskets while intallation adn removal. I would recommend you take off the sensor if someone else is filling the air for you. Also, it's normal to loose a little air and hear the hiss when installing them as they compress the stem to detect the pressure. I contacted customer service for help on this and resetting the sensors. They communicated very well explaining on resetting procedure and sending me two sensors quickly and free of charge! Only thing I don't like about this product is the fact you can't change the temperature to farenheit! Hope this helps!

First experience with a TPMS. Excellent product, thoughtful packaging, reasonably good instructions. Comes with tools and even seals for use in future if batteries need replacing. Easy to install once you figure out that you place the rubber gasket inside out so that it pooches out in a floppy way that is only temporary. After the nut and sensor are placed, it pops out to securely cover the connections. Be patient for the monitor, as it took about 10 minutes of driving for last of the sensors to register. Very accurate!

Pros: (1) Sensors are a subtle black, no design or logo, so they blend-in fine. (2) Sensors are easy to install (LCD display has a flaw, see Con # 4 below). (3) My kit contained rubber "dust caps" for each sensor that provided a type of seal around the cap that I'm sure would help for longevity. These were not pictured in the listing, and the instructions for them was a separate supplement so these appear to be an excellent, new addition to the kit. Cons: (1) You can only set one default value for the High Pressure Alarm & another for the Low Pressure Alarm (some TPMS brands allow you to set values for each tire). This is only important for vehicles that have different recommended inflation values for front & rear tires - e.g., a pickup truck. (2) If a sensor loses its wireless connectivity, the Low Pressure Alarm will sound ... and sound ... and sound. If you unplug it to make it stop, see Con # 4 below. (3) I knew my tires needed some air so I checked each tire's PSI & then I installed the sensors. I was initially VERY impressed as the PSI's matched. Then I removed the sensors, added air, and reinstalled the sensors. The directions say that you must drive (I believe 20 MPH? - I'd have to check the manual) so the sensors detect the pressure change. Well, I drove and drove ... and then drove some more ... and the pressures never updated, they stayed at the initial pressure before inflation - and that makes me wonder if they would truly detect a change in pressure (e.g., "leak") while one is driving. I have my doubts ... (4) Every time the 12v "cigarette lighter/adapter" digital display loses power, ALL of your settings are lost (units, high/low pressure alarms, the orientation of the device if you decide to re-orient it 180-degrees to move the USB changing port, etc.). So - if your vehicle doesn't maintain constant power to that 12v outlet, you'll have to spend time setting-up your values every time you turn off your vehicle! There should be a battery back-up in the display that stores the settings. In the end, I sent these back to Amazon. Maybe I'm an outlier - because the overall product rating for this is really good - but frankly I can't understand why the rating is so high. There are too many flaws.

Works well. Biggest issue I’ve had is getting all 4 tires connected correctly. Took some time but now they are all connected seems to work fine

So I really like it so far! Thank you very much for a dope tool. It’s handy it literally is for you to always remember and not to neglect small details bout your car. Like no one thinks of tire pressure everyday like that. But it’s good to have numbers in front of your eyes, just in case. Before I installed I felt my tires going a lil different than when I just bought my vehicle. It’s been a month since and I put the sensors on and it did indeed show pressure was slightly lower since the purchase date. So pretty accurate. When I got to good year they were confused by lil guys they said they never seen these before. Idk man you still need to do the work and never neglect your baby so I filled some air at the good year because I don’t want to go down when the sign would pop up on my dash. Sensors do help to keep you in check. I’m ocd I like clarity and sharpness so it works for me. Thank you. I hope they serve well and consistent.

UPDATE: So finally received my two replacement TPMS units from Amazon. Only one TPMS works well enough for me to keep. The other one will only connect up with a single tire sensor. The other three sensors are DOA. Unbelievably poor quality control for a product listed so highly by other reviewers. Suspect that the tire sensor, at the very least, have batteries in their sensors which gradually run down and are essentially devoid of any voltage by the time they actually reach the consumer. VERY DISAPPOINTED! Have had several similar 'add on' Tire Pressure Monitoring Systems (TPMS) over the years. Two of my cars TPMS recently failed and decided to invest in new systems rather than trying to change the batteries on these outdated units which were already several years old by now. Decided on this Tymate Tire Pressure Monitoring System based on the reviews and description of the product. Received two sets of these tire monitors and installed them easily and quickly. Both my daughter and I who were using separate cars noticed that after driving for several minutes the Tire Sensor Monitor was only able to link up with two of the four tire sensors. All other systems I have purchased were able to immediately sense all four tire sensors once the speed exceeded 12-15 MPH. Don't know what the issue is but setup is NOT easy as described by others! Looked for an explanation without success in the several informational guides that came with the units. Amazon said to try two other units and agreed to immediately send out replacements but I had to repack and ship the old units back to Amazon and this was just an extra waste of time and hassle for me. So far it has been anything but a satisfying or easy experience trying to use this TPMS.
